The lesson of Argentina over the past 15 years is that, unfortunately, it's much rarer than it should be to see a country that zigs when it should zig and zags when it should zag. Orthodox policies would be right for Argentina today, but instead they're sticking with heterodox policies that were appropriate in 2002. Most rich countries, meanwhile, could use a dose of heterodoxy right now but are sticking with orthodoxy instead.
